Specification of Lettera Patent. g

Patented June 22, 1920.

Application mea my 1e, 191s. semi yminuterie.

To all whom t may concern:

Be it known that I, FREDERICK C.' WARNE, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Disk Harrows, of` which the following is a Specification.

My yinvention relates to improvements in disk harrows, and more particularly to that class ort'ype known as double or tan' dem disk harrows, in which front and rear units are employed, each unitk embodying a pair of adjustably mounted vrotary disk gangs adapted vto be angled or turned in opposite directions .relative to each other and to the line of draft, as disclosed for example in Patent No. 1,189,890, of July 4th,

This inventionifurtherrela'tes to that class or type of double disk harrows know-ny as engine disk harrows, the present improve-- ments being particularly designed land in connection with an en'- adapted foruse and with this end in view,

gine or tractor,

my improvements relate particularly `toy improved draft connections `for such implements and improved lever and lever actuated lockingA and adjusting mechanism whereby 'the disk gangs thereof may be readily moved to and secured in any desired angular position relative to each other and Y draft by the operator of the.

to .the line of tractor while in the seat or cab of the. lat- ;fter, theconstruction and arrangement of lthe parts 'being such that when the disk locked in their normal working or fully angled osition, or in an intermediate angular wor ing position, and are rela.- tively released or unlocked by the operator through such mechanism while the tractor is in motion, lsuch disk gangs will automatically -`vassume through such draft connections their non-working or non-angled transporting position, or less angular working positio as the case may be, and as and' may be stoppald t e gangs are and locked in such elected positionwhile 'tractor is,- in motion. Furthermore, if desired, the disk gangs may f be manually moved to a .morefangularor to a fully angled working position, while in motion, through a sing e hand lever with a miniimproved lever actuated disk harrow of this class having its parts `so constructed, ar-

`inbefore referred to,` such connection with the front ,harrow section, however, in the present instance, being effected through relatively movable draft connections operable and adjustable on' the front or draft framethrough the medium of a single-hand lever within ready reach of the operator of the tractor.`

' With the above mentioned and other ends in view, the invention consistsin the novel construction, arrangement, and combination of parts, lhereinafter described, illustrated in one of its embodiments -in-"theaccompanying drawings, and particularly pointed out vin the appended claims;

Referring to the drawings, forming a partl of this specification, Figure 1, is a top plan view of a disk harrow constructed inac-v cordance with this invention, the disk gangs 1 being in their non-working or non-angled transporting position, the hand -lever be- -ing shown in section and. the scraper blades being removed for the purpose illustration of the parts.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

The improved barrow or tillage implement comprises a. front harrow section or unit and a rear or trailing harrow section or unit. The front and rear harrow sections may be of any suitable and conventional form, and for the purposes of illustration l have shown my improved draft appliance and its connections applied to or embodied in a double or tandem disk'harrow of the general form of that disclosed in my former patent hereinbefore referred to- The front harrow. section or unit is provided with` a suitable draft frame consisting, in the present instance, of a transversebar 1, and a curved draft frame member 2, the

latter having its forward middle 'portion secured to a stub-pole 3, which latter isl made up of spaced angle bars secured at their rear to the transverse bar` or member-1, and, in the present instance, forming a guide or slideway for the improved longitudinally movable draft appliance hereinafter described. ,Y

As a means of connecting the draft frame to the front disk gangs 4, draft bars or links 5, are pivotally connected to filler blocks 2, said draft bars extending rearwardly beneath the transverse bar 1, and being flexibly connectedto the axle boxes 6, somewhat beyond the centers of the disk. gangs, so that the inner ends of the latter will have a tendency to swing rearwardly and assume a rearwardly converging position. As a means of supporting and maintaining the draft bars 5, in proper horizontal relation to the transverse bar l, supporting clips 7, are pivotally mounted upon the filler blocks 2, and are secured by means of pivot bolts 5a, secured to the forward ends of the draft bars 5, said clips A7, extending rearwardly and being secured to the top intermediate portions of the bars 5, by means of pivot bolts 7, and as a further means of seeuringthe draft frame to the front disk gangs draft bars or links 8, are connected by the pivot vbolts 5a, above f the supporrtingclips 7 and extend upwardly and rearwardly and are flexibly connected' to the upper or transverse bars 9, of the front gang frames by means of pivot bolts 9a. The gang frame bars 9, are connected to the-disk gangs 4, by means of supporting' bracket or brace members 9", extending downwardly and suitably secured to the axle boxes 9. v The rear harrow section or unit, in the present instance, comprises a pair of rear disk gangs 10, suitably mounted and supported in gang frames 11, the latter beingv provided with supporting brackets 11, connected to 'axle boxes 12.

The rear disk gangs 10, in the present instance, are pivotally connected and held in proper spaced relation at all times by means of a transversely extending rear flja'ii forming a rear harrow frame 13, provided at its ends with pivot bearing bolts 14, suitably connected to the rear gang frames 11, of the rear gangs. It will be observed that the pivot or swivel bolts 14, are located beyond the centers of the rear gang frames, so that the inner ends of the rear gangs, if left unsupported' or free, will have a tendency to swing rearwardly and away from their normal forwardly converging working position,

as shown in Fig. 3, of the drawings, and

assume a strai htened non-working position relativel to eac other, as shown in Fig. 1, of thedrawings, when permitted to swing on their pivots 14, through their draft connections, yas hereinafter described.

As a means of connecting the inner ends vof the rear gangs `10, to the front harrow wardly and being secured, in thepresent l instance, to the transverse bar 1, and between the members of the stub-pole 3, `by

' the rear gangs in a rearwardly diverging relation, and as compared with the movements of the draft bars attached to myA improved draft appliance hereinafter described, these draft bars 15, together with the draft bars or links 5 and 8, are lon i, tudinally fixed relative to the frame units and tillage gangs, in order that the functions of the draft appliance and its longitudinally movable draft bars may be performed, as hereinafter described.

' Referring now to the improved draft ap- -pliance and its gang connecting, adjusting and controlling mechanism, whereby the op- .erator of the tractor, while in his usual driv- 'ing position on the latter, and when the disk gangs are locked in their normal or fully .angled positions, or in intermediate angled positions, and are relatively released oriunlocked while the tractor is in motion, will permit such gangs to automatical'l assume,

through such draft connections t eir nonworking non-angled transporting position, or various angular working positions, as the case may be, and as the operator may elect, and whereby the same may be stopped and locked in any such elected positions, it'will be seen that the improved draft appliance comprises a longitudinally movable draft member or element, mounted, in the present instance, in the stub-pole 3, of the draft frame, and consistin in the present instance, of a draft bloc or head 17, adapted to slide along the angular members of the stub-pole 3, said block 17 being controlled by a longitudinally movable draft bar vor yoke 18, terminating at its forward end in a draft loop 18a. The draft loop 18, is adapted to ybe attached to the tractor, and as a means of operating and controlling the movements of the draft bar or yoke 18, and draft head 17, and the connections leading from the latter to the disk gangs, as hereinafter described, one side of the draft bar or yoke 18, is provided with a toothed rack 18", and as a means ofV enabling the operator to readily move the draft block or head 17, and its attachments, together with the stub. pole 3, and its attachments, `relative to'eacli other, an operating hand lever 19, is piv-k otally mounted on the stub-pole 3, through said hand lever extending upwardly through a suitable guide bracket or segment 20, and

within ready reach of the operator of the tractor.

Asa meansl of intermittentl 'engaging and lfeeding the draft bar or yo e'18, rearwardly through working impulses imparted to the hand lever'19, the lower portion of the latter is provided with'a pivoted pawl 21, adapted to be moved to a released position by means of a rod 22, leadin to afreleasing lever 23, at the handle portion of the hand lever 19.

As a means of preventing any shifting or retrograde movement of the draft bar 19, and toothed rackV 18", after each working impulse given to the'hand lever 19,`the stub-pole 3, 1s provided' at one side with a pivoted locking dog 24, the latter being provided with a detent 24, adapted to normally ride upon the teeth ofA the rack 18", and as a means of simultaneously releasing the pivoted pawl 21, and locking dog 24,

and holding such parts in such released position for the extended shifting or forward movement of the draft yoke 18. and its attachments, by the 'forward draft of thetractor, the locking dog 24, is provided with .an overhanging ledge or projection 24", so that when the free end of the pivoted pawl 21 is moved in an extended upward direction it will enga e with the overhanging ledge 24", and raise and hold the locking dog 24, out of engagement, as shown in Fig. 7, ofthe drawings. i

As a means of permitting a limited movement between the draft bar or yoke 18,.and the draft block or head 17, the upper and lower plates of the'draft block are connected by means of vertical bolts 17, surrounded by spaced sleeves or spools 17", the latter being permitted to slide o`r travel in the slot or guideway 18, formed bythe spaced sides ofthe draft yoke 18, and it is obvious that this slotted arrangement between the bar or yoke 18, and the rear sleeve or spool 17", of the draft block will permit the draft bar 18, when the implement is in the position shown in Fi 1, or when detached, or when the tractor 1s| slackened, to be moved rearwardly from'the osition shown in Fig. 1, to that indicated 1n Figs. 3 and 4, without moving the draft block 17, and its connections, so that when the disk barrow is attached or moved forwardly the disk gangs will assume a predetermined angular position, in accordance with the position given to the draft bar or yoke 18. The draft connections or bars, leading from the draft appliance to the front and the rear disk gangs,l comprise longitudif nally movable draft bars 25, leading from the draft block or head 17 and connected.

to the inner ends of the front disk gangs, through the medium of pivot bolts 25, se-

cured to the inner axle-boxes 6, said `draft bars 25, being provided with upwardly' and rearwardly extending draft links 25h, connected to the inner ends of the bars 9 of the front gang frames by means of ,pivot. bolts 25, and the draft connections, leading to the rear gangs and the ends of the rea-r frame unit, comprise rearwardly diverging draft or reach bars' 26, the latter, in the present instance, being pivotally connected to the pivoted portions of the rear gangs byv means of bearing plates 26a, 'said bearing plates 26, being suitably secured to the gang frames 11, and surroundingthe pivot bearing bolts 17, and by reason 'of thisconstruction it will thus be seen'that the draft or reach bars 26, are indirectly connected to v As a means of flexibly connectingA the forward ends of the draft or reach bars 26,'tov

the ends of the draftI links25", as well as equalizingV the draft movements or stressesgiven to the draft bars 26, and also iding the latter land the-draft links 25", 1n their forward and rearward movements in ad'usting the disk gangs, the forward ends'o the draft or reach bars 26, are pivotally con` nected to a transversely extending equalizing bar 27, fiexibly connected to the rear ends of the draft links 25", by means of flexibly connected links 28, and as'a means of longitudinally and vertically guiding the equalizing bar 27, and its connections, the equalizing bar 27, Ain the present instance, is provided with guide Sleeves 27, and a cross guide plate 27", connected by means of connecting bolts 27e, said parts 27a and 2.7", forming a' guide opening to y receive and contain a` guide member 16, formed at the Vrear end of thefixed draft element or median reach bar 16.

It will be seen that 'the connections of the draft links 25", with the links 28, and the connections of the latter, with the equalizing bar 27, and the ivoted connections of such equalizing bar 2 with the forwardly converging reach bars 26, are arrangedat points equally distant from the longitudinal center of the harrow or the line of draft thereof.

When' the disk gangs are in their nonangled or arallel transporting position, as shown in ig. 1, of the drawing, and it is desired to positively prevent any rearward travel or retrograde movements of the draft bar or yoke 18, while being trans orted, the rear end of.` such draft bar may e blocked orA locked b throwing the pivoted vbail member l29, rom its full line released position, shown in Figs. 1 and 3of the drawings, to its dotted line position, shown in forwardly relative to the fixed draftmem- Fi 1, of the drawings, thereby positively loc ring the parts so that the disk gangs will be positively held in their parallel transyoke 18, being attached to a tractor, or in other words being anchored relative to the front draft frame, as the hand lever 19 is worked rearwardly, the stub-pole 3,' and the draft frame member, and its connections, and relatively lon itudinally fixed draft bars 5 and 8, and xed draft bars 15, connected to ithe 'reach bars 16, will be moved forwardly relatively, thereby carrying the pivjote'd portions of the front disk gangs and the innerportions o f the rear ydisk gangs bers gand imparting an angular position to the salme in an obvious manner., 1n view of the constructiqn labove described and as ,illustrated inthe accom anying drawin As a means 'of vertical supporting t e 90 inner ends of the rear ti lage gangs in .a common horizontal plane in their various adjustedpositions, the rear frame unit 13, is provided with brackets 30, said brackets 30, being provided with guide slots 30, adapted to. 'slidably receive and contain horizontally extending guide straps 31, suitably secured to the inner ends of the rear gang frames.
